Right, but you're questioning a position that doesn't really exist. Pretty much everyone that is a strong advocate for labour protections would also like universal healthcare, it's just much more likely we can achieve labour protection in the short term than universal healthcare.
Sure, but if that is your position you should go out and advocate for this better thing instead of bemoaning the efforts other people are making as misplaced.
This shows up anytime people try to make some sort of progressive improvement to society, people come out of the woodwork to complain that it's not the right solution, without doing anything (other than complaining I guess) to motivate a better solution.
